短暂性脑缺血发作病人经颅多普勒分析

ANALYSIS ON TRANSCRANIAL DOPPLER IN 38 PATIENTS WITH TRANSIENT ISCHEMIC ATTACK

目的:评价经颅多普勒超声(TCD)对短暂性脑缺血发作(TIA)的诊断价值。方法:应用经颅多谱勒超声对38例短暂性脑缺血发作病人进行检查。结果:38例TIA患者进行常规TCD检查,其中脑动脉硬化26例,占68%,其中血管狭窄14例,占37%,血流速度减慢12例,占32%,血管痉挛8例,占21%,正常4例,占11%,总异常率89%。结论:TCD检测对于诊断TIA有重要的临床意义。

Objective：To appraise the diagnostic value on Transcranial Doppler（TCD） in transient ischemic attack（TIA）. Method：38 patients with TIA were examined by TCD. Results：In 38 patients with TIA ,26 cases were cerebral arteriosclerosis （68%）, 14 cases were vascular stenosis （37%）, blood flow of 12 cases was slow（32% ） ,and 8 case have vasospasm （21%） ,4 cases are normal（ 11% ）. The total abnormal rate is 89%. Conclusion：TCD has important clinical significance in diagnosis of TIA.
